"I’ve been playing since I was young," she said shortly after her overwhelming horse victory. "I do it more than anything because it’s fun. I see a soccer ball and I turn into a little kid, I love it very much."

The world of freestyling isn't exactly awash with females, making Castillo a rarity. "I wanted a way to compete against the guys, I decided to start doing tricks in high heels. As far as I know, I'm the first girl to do this."

The 24-year-old, visiting Brazil from her native Buenos Aires, also feels that she has inspired other members of her gender to follow in her footsteps. "After my videos came out, I began seeing other girls doing the same thing. I think it’s great, that us women can also be included in a sport that’s dominated by males."

While filming with Yahoo, Castillo happily posed with fans (she is relatively well known in South America) and was very happy to play keep-ups with the Colombians, Argentines and Brazilians who had gathered to admire her skills.

Perhaps next time I'm drawn into a freestyle battle, I should bring a pair of heels ...
